Research On Computer Interlocking Teaching And Training System Of High Speed Railway

Computer interlocking system is the core of signal control system of high speed railway station, and the correct operation and maintenance of the system is the key to ensure the safety and efficiency of the station. The practical computer interlocking system is in all-weather continuous working condition and closely associated with the interface system and the operation of the system is related to traffic safety and the plan schedules' accomplishment which cannot reach the demonstration and practice requirement of the railway staffs. Meanwhile, the practical computer interlocking system is large and costly and it is difficult to set up an interlocking simulation platform with complete function and certain scale for personnel demonstration and practice. So it is of great significance to develop the computer interlocking teaching and training system with high integrated degree, simple operation condition which can reach the function requirement of training guidance and training exercise for demonstration and practice.In this thesis, the function implementation and communication interface schemes are proposed accordance with the requirements of the relevant norms and detailed functional analysis of computer interlocking teaching and training system. And the system's completed model, levels and modules divisions given through the object oriented method and UML modeling language, and then the software simulation platform was built.The research contents of computer interlocking teaching and training system of high speed railway are as follows:(1) In accordance to the functional requirements and organizational structure of the high-speed railway computer interlocking teaching and training system, the system planning and design was given from the three aspects of users in the field to the actual demand, system functional requirements, system performance requirements based on detailed theoretical analysis and technical analysis.(2) According to practical teaching and training requirement, text training and station field synchronous demo approach was chosen and concrete design of high speed railway computer interlocking teaching and training system was proposed from the selection of integrated display of man-machine interface, basic operation training mode and the communication protocol and other aspects.(3) The system software simulation environment was completed and the use case diagram, class diagram and the state diagram of the key parts of the system were established by using the UML modeling language. Each modules of the high speed railway computer interlocking teaching and training system were realized through the Visual Studio Microsoft 2005 platform.High speed rail interlocking computer teaching and training system was used in Luliang station of Wuhan Railway Bureau and Heliu station of Kunming Railway Bureau and the modify and upgrade of the system has been completed according to the actual installation and use feedback. And now, the final software testing was fulfilled and consigned to use.
